HDCP Block
The HDCP block implements the datapath decryption block of the HDCP content protection scheme
of DVI. Please refer to the HDCP Specification 1.0 for details. The state machines of the HDCP
specification are split between the external microcontroller and this block. Only the high speed and
data intensive cryptographic functions are implemented in this block to maintain maximum system
level flexibility.
